They are out there but are hard to find and hard to get. I might have one in the garage, i'll look.

Andy are you selling the battery trays yet??? Nicely done

They are called display batteries. They turn up on epay every once in a while. Have converted a couple of them. Much cleaner than doing it with a wet battery.

No I decided not to sell them. They aren't a bolt in deal so they would be a hassle to sell.

That is what I am thinking John, not having to mess with acid and lead if I don't have to. Hopefully Badfish can find one but Ill also check on ebay. If you run into any, please let me know.

Thanks

27 series? Just checked a minute ago. No 27's, and no 24's. You might check your local parts stores and ask if they have any stuck away on their back shelves. Paid $10.00 for one years ago to one of my customers I had been calling on for years. You wouldn't have wanted that one. It was a 24 Delco.

I am not up on my sizes that I need, I think the 27 is BB size and 24 SB? If that is correct, then yes, I would like to find one of each. I can ask the local auto parts places next time I am in there.

It's not as fun as a day at the ballpark. I'm going through that right now.

A new start for my 77 Cordoba

I just gutted group 27 Mopar restoration battery. Had to cut the top off with a sawsall, I tried removing the plates from below and there was absolutely no possible way to do it from below on the Turbostart 2011 I was working on. Turned out GREAT, but it was a hassle.

I've done some damage trying to do it that way, as you can see. Though I'm not sure the damage didn't exist as cracks before I started from freezing, swelling, etc. It's doable, but messy. Cutting the top off is plan B. Mine is also a Turbostart c1995.

I have been checking these out as well! I worry though. I have a few loads. Electric water pump, turbo oil scavenge pump, small radiator fan, EFI system coil on plug and injectors. maybe the next size up??

One other question. What are you using to charge it? I do run a tiny Denzo style alternator. But on my optima I still need to charge between rounds. I did remove a huge electric fuel pump..

I use a Remy 21798 alternator. It is 105 amp and weighs about 12 lbs. It is commonly available at just about any parts store. I run on Drag Week which involves street driving, plus there is no way for me to plug in a charger at the track. So I need a powerful alternator that I can buy anywhere in case it fails on the road, even tho it is heavy.
Edit: THis alternator is for a 1999 - 2004 silverado 1500. It is about the most power you can run off a single V belt, and it needs to be TIGHT. It comes with a serpentine pulley, and I had to put a V pulley on it. So if it dies on the road, I will have to swap the V pully onto the replacement alternator.

Might not be a bad idea to go up one size. But if you have enuff alternator, the bigger battery will only give you more reserve for running stuff when the engine is off. This one certainly has enuff oomph to start the car.

Not only did I save the weight of the battery, I saved about 20# of cable by mounting the battery a foot away from the starter on the inside of the frame rail, instead of in the trunk. The NHRA mandated battery cut off switch is right there too, with the lever of it on the floor inside the car where I can reach it if I forget to turn it on. A 3/8" x .030" wall stainless steel tube runs from the lever, back through the trunk and out the back of the car as a remote control for the switch. That is much lighter than a Morse cable, it only weight a pound.

Those smaller batteries can tuck in some of the tighter areas. I didn't think about putting it closer to the starter.

Dyno - Can you fill that crack with some melted plastic? If you can, I would drill a hole on the ends of the crack so it won't keep cracking, then try to fill that and the crack with some hot black plastic. Looks like a ton of nastiness in that old battery of yours!

What is everyone doing with the old acid and lead plates from the batteries you cut open?

I'll do something to address it for sure. Epoxy, Gorilla Glue, some sorta something. Doesn't have to be water/acid tight or structural. All for appearance, and completely covered on the sides by the Thermoguard. I'll find something that will work.

Yes, fairly messy in there, though I've managed to do it fairly neatly from a work area point of view. I have a 5 gal. bucket with a heavy mil contracor garbage bag that all the contents are going into. Our county has hazardous waste collection days 3 or 4 times a year, and they take car batteries. So I'm going to give it to them.

I love the lithium battery upgrade. But knowing how hot they get in computers and phones, I worry about one in a hot engine compartment. Unlike a modern hybrid or BEV, where the battery is liquid cooled and computer monitored, mine will just have a 40 year old plastic Thermogruard with airflow through the core support around the repro case. Almost wondering if I should leave the hole in the side of the case!

You could probably wire in a computer fan or two, the style that cools the cases of desktops. You can get them in a variety of sizes, even look for people throwing out old computers for trash. They usually still have the fan(s) in them. Can put one in the back or bottom or where you really can't see it and have some ventilation holes in another location. What about sitting the battery on some aluminum / make a heat sink?

Whats the voltage on those computer fans
